JLR fits twin turbos to Range Rover Sport

The 2017 Model Year Range Rover Sport is the first full-sized Land Rover SUV to feature a four-cylinder diesel engine with twin sequential turbochargers.

The 2-litre SD4 Ingenium produces 240 bhp and 500Nm of torque, and is claimed capable of returning 45.6 mile/gal on the EU combined cycle with emissions of 164g/km (manufacturer’s estimated data).
The introduction of a second turbocharger to the Ingenium engine has been significant in retaining the impressive power output and strong torque characteristics familiar to Range Rover Sport customers. The advanced engine is the first Jaguar Land Rover-built unit to feature series sequential turbo technology.
Vehicles fitted with the new engine will be distinguished by a single twin-exhaust configuration. Other derivatives retain the existing set-up, with a single exhaust on each side of the rear bumper.
Elsewhere in the range, the 3-litre V6 supercharged engine features lightweight all-aluminium construction. Combining supercharging with direct-injection and variable intake, as well as incorporating exhaust valve timing, this engine also has a single balancer shaft to enhance smooth-running and refinement.
The supercharged V6 achieves 340 bhp and 450Nm of torque combined with CO2 emissions of 243g/km. JLR claims a 0-60 time of 7.1s. In contrast, the latest twin-turbo engine gives a 0-60 time of 8.0s
